1.Let the system of linear equationsx+2y+z=2αx+3y−z=α−αx+y+2z=−α\begin{aligned} x + 2y + z &= 2 \\ \alpha x + 3y - z &= \alpha \\ -\alpha x + y + 2z &= -\alpha \end{aligned}x+2y+zαx+3y−z−αx+y+2z=2=α=−αbe inconsistent. Then α\alphaα is equal to:a.27\dfrac{2}{7}72b.−27-\dfrac{2}{7}−72c.72\dfrac{7}{2}27d.−72-\dfrac{7}{2}−27Login to continueOnly logged in users canattempt or see the solution.
